RICHARD BRADBURY. AND DAVID XVINTERBOTTOM, OF OLDHAM, ENGLAND MEASURING-VESSEL FOR FILLING INK-WELLS.

SPECIFICATION forming part. of Letters Patent N 0. 455,734, dated July 14, 1891. Application filed July 23, 1890- Serial No. 359.585. (No model.)

To all whom it may concern.-

Be it known that we, RICHARD BRADBURY and DAVID WINTERBorroM, subjects of the Queen of Great Britain, residing at Oldham, county of Lancaster, England, have invented certain new and useful Improvements in Apparatus or Vessels for Delivering Measured or Regulated Quantities of Fluids, of which the following is a specification.

The invention may be used fora variety of purposes; but its primary use is to deliver stated quantities of ink into ink-wells in schools or public institutions or other places where ink-wells require constant refilling.

Our invention will be best understood from the following description and by reference to the annexed sheet of drawings. I

Figure l is a vertical section of the apparatus in an upright position. Fig. 2 is a similar View of the apparatus in a tilted positionas, for example, when pouring out the measured supply of liquid. Fig. 3 is a horizontal section of Fig. 1 at the line A B. Fig. 4 is a portion of a vertical section at the line C D, Fig. 1.

The apparatus as illustrated consists of a cylindrical vessel a, provided with a handle I) and delivery-spout c. The vessel ais divided vertically into two unequal spaces a a bya partition d, and at the top of the partitionin the lesser space or discharging-chamber a we place a measuring-chamber e, which communicates with the supply-chamber a by a port 6, out in the partition d opposite to the meastiring-chamber e. The chamber 6 also communicates with the discharging-chamber a by means of a hole e in the bottom of the chamber. Opposite to this hole is a swing valve or stopper f, carried on aweighted bellcrank lever f and pivoted at f The arm of the lever f which carries the stoppervalve f, lies at such an angle that when the vessel is in an upright position, as in Fig. 1, the stopper-valve is clear of the hole e but when the vessel is tilted, as in Fig.2, the hole is closed by the valve, the vertical weighted arm of the bell-crank lever f keeping the valve against the hole. The capacity of the measuring-chamber e is increased or diminished by raising or lowering the slide g, which slides in ways 9, and is operated bythe spindle g passing through a packed gland, as

shown, and fitted with a milled knob g? for convenience in handling. By raising the slide g to the top the measuring-chamber might be,

if desired, entirely out off from the supplyof the funnel is closed by a removable stopper 7. 1

To preserve an equilibrium of atmospheric pressure in the chambers a and a we provide air-tubes is Z. In using our improved apparatus we fill the compartment a with ink or other liquid to a convenient level, and close the funnel with the stopperj. YVe then adjust the slide 9 to give the required capacity to the measuring-chamber e and tilt the vessel into the position shown in Fig. 2. By this tilting the liquid finds its way into the measuring-chamber e. In this tilted position the chamber 6 is closed at the foot by the valvestopper f, as clearly shown in Fig. 2. Upon causing the vessel to resume the perpendicular position, as shown in Fig. 1, the valve f falls away from the hole in the foot of the chamber e and allows the liquid in the chamber e to fall into the discharge-chamber a. The apparatus is now ready for use, and upon each occasion that the liquid in the dischargechamber is poured out or delivered, as shown in Fig. 2, the tilting of the vessel causes the refilling of the chamber 6, and the subsequent delivery of its measured contents into the discharge-chamber a, thus replacing the liquid which has just been delivered.

To prevent the nose of the spout c from dipping too deeply into the ink-well or inkstand, we place upon the said spout-nose a curl of wire 117., having projecting ends, which act as trunnions, which rest and roll on the top of the ink -well. Instead of the said trunnions, we might have a collar with air ports or slots.

Although we have instanced our invention as particularly applicable to the filling of inkwells and the like, it will be understood that it is applicable to all purposes in which measured or regulated quantities of liquid'are to be delivered in a cleanly, certain, and expeditious manner.

We claim as our invention- 1. An apparatus for delivering measured or regulatedquantities of liquid, consisting of a vessel a, with spout and handle, divided by a partition d into two unequal compartments, and provided with a measuring-chamber com municating with both compartments, swingvalve, adjustable slide, filler, strainer, and airtubes, substantially as described and shown.

2. In apparatus of the indicated nature, the measuring-chamber e, in combination with the swing-valve f and adjustable slide g, for the purposes and substantially as described and shown.

3. As means for determining the capacity of a measuring-chamber, in apparatus of the indicated nature, the slide g, forming one side of the chamber and capable of being adjusted by means of a spindle g passing through a packed gland and provided with a knob, substantially as described and shown.

4. The combination, with the vessel and its lateral pouring-spout, of the supports or trunnions rigidly attached to said spout near the delivery end thereof and on which the vessel may be steadily rocked in pouring, liquids, substantially as set forth.

5. In a measuring-vessel having receiving and delivery compartments and an intermediate measuring chamber communicating with both of said compartments, a valve for shutting off communication with the deliveryoompartments While the measuring-chamber is being filled by tilting the vessel, and a-delivery or pouring orifice for the deliverychamber, substantially as set forth.

In witness whereof we have hereunto set our hands in presence of two witnesses.
